Abstract

The present investigation aims at studying the effect of application of biogas manure and filter cake (Filter mud), as a natural soil amendments, on improving some properties of desertic soils and their implications on barely plant grown thereon. A pot experiment was carried out at the greenhouse of soils and water department, Faculty of Agriculture, Benha University, Egypt, using perforated PVC pots of 5 kg capacity and barley (Hordum vulgare cv. Giza 123) as a test plant. Two surface soil samples (0 - 30 cm) differed in their texture and calcium carbonate content, were collected, to achieve these aims, from El-Hammam region, North-Western Coast of Egypt, to represent desertic soils. Biogas manure and filter cake (filter mud) were added at a rate of 0, 1, and 2 % (w/w) and thoroughly mixed with the soil and incubated for two months at moisture content equivalent to field capacity. Ten grains were planted in each pot. Irrigation was done with tap water so as to reach the water holding capacity of the soil. After complete germination plants were thinned to 5 per pot. Macronutrients of N, P and K were added to all pots according to the rates equivalent to those recommended by the Ministry of Agriculture. The experimental design was factorial randomized complete block design with two factors, in three replicates. At maturity, plants were harvested and soil samples were taken from each pot for physical and chemical analyses.
